How to express dependencies between graphs

Description:

Graphs that are published in a dataset or the "open" web often rely on definitions in other graphs. OWL has a property owl:imports to express that when an OWL file is parsed then the axioms from imported graphs should also be included (for inferencing etc). RDF(S) does not have such a facility.

Although many applications may take complete control over what graphs are needed for shape validation, it would be useful to be able to say that my published graph needs definitions from another given graph, and to point from a graph to the shapes graph that should be used for validation *by default*.

A possible design would include two properties
1) sh:include - points from a graph (e.g. of instances) to other graphs (e.g. of class definitions)
2) sh:library - points from a data graph to a graph with shapes definitions

So the main question here is whether SHACL should have such properties at all (and possibly a class sh:Graph to represent the graph itself). I anticipate that some people will argue that adding such information into the graph itself limits its potential for reuse, but in many cases there are pretty obvious default interpretations that should be followed, esp if shapes are linked with classes.

If the WG decides against such properties, we need to at least explain users how they are supposed to publish any data that is discoverable by generic constraint checking applications.
